This is a workspace dump of the current progress on llvm-tapi for ELF. Subject to change, open to feedback. Program headers and .dynamic section are not handled in write process yet.

Added:

- ELF binary write support:
  - ELF header
  - Section headers
  - .dynsym, .dynstr, .def (SH_NOBITS), .shstrtab
- Output format selection via a crude flag.
- Additional integration tests.

Fixed:

- ELFArch now conforms directly to the architectures in the ELF namespace.
- Fixed bug where converting to an ELF binary would throw an unsupported error.
- Fixed TBE YAML so that .tbe files with no specified symbols would load correctly.

Changed:

- ELF_DSO file type has been replaced with ELF_[32/64][LE/BE].
